I guess the reason I've never actually noticed this is purely because I normally don't write discs with more than about 4.35GiB. Normally I aim to make sure they are closer to the 4GiB mark. This leaves just that little bit of extra space at the edge of the disc, just in case someone isn't quite as careful as I am, and leaves partial finger prints on the outside edge of the disc.
So my rounding of using 4700000000 bytes is not so wrong after all, I haven't had problems with it. ;-)
If the size you use is about that, no it's not that far out.
I should modify it to 4699998208 or 4700000256, the closest 2048 multiples.
You'll want it a multiple of 32768 due to the fact that the sectors are usually written[0] in blocks of 16[1], so you'll want either 4699979776 or 4700012544. [0] and, since read-ahead is employed, probably read as well. [1] Executing 'builtin_dd if=blank.image.iso of=/dev/dvd obs=32k seek=0' ^^^^^^^ as seen in this output from growisofs.
